Temporal and Spatial Distribution Characteristics of Rainstorm in China Based on CMORPH Integrated Precipitation
Published 2020-01-01“…Based on the data set of China automatic station and CMORPH precipitation product fusion grid,this paper analyzes the spatial-temporal distribution characteristics and change trend of rainstorm number and rainstorm amount in 2008—2016 in China by the methods of rainfall object identification and Theil-Sen estimator.The research shows that there are 24 676 rainstorms in 2008—2016,including 20 135 small rainstorms,4 230 heavy rainstorms and 311 extremely heavy rainstorms.The rainstorm events in the whole year are at most in 2012 and at least in 2011with only 42,which occur frequently from May to September,accounting for 80.8% of the whole year.In 2010,2012 and 2014,the rainstorms in the coastal areas of South China and North China accounted for a relatively high proportion,some of which reached more than 60%.In 2008,2013 and 2016,the rainstorms in the coastal areas of South China and Hubei accounted for a relatively high proportion.From May to September,the rainstorm in China is widely distributed with large amount,mainly in the Pearl River Estuary,Northeast Jiangxi,and coastal areas of Hainan,Taiwan,Zhejiang and Fujian,with an annual average monthly rainstorm of about 150 mm.The number and amount of rainstorms are decreasing from the southeast coast to the northwest inland,with high value areas mainly in South China and the middle and lower reaches of the Yangtze River.The distribution of small rainstorms is similar to that of the total rainstorms.The heavy rainstorms are mainly concentrated in the coastal areas of Guangdong and Guangxi,the eastern Hainan and the southern Taiwan.Extremely heavy rainstorms are scattered in Southeast China.In the past 9 years,the number of rainstorms has increased,especially in South China and the middle and lower reaches of the Yangtze River,with significantly increased amount.…”

Impact of High-standard Farmland Construction policy on labor substitution by machinery in China:Evidence from quasi-experimental approaches at the macro and micro levels
Published 2024-12-01“…[Methods] Rooted in the induced technological changes theory, this study employed the difference-in-differences (DID) method to assess the impact of HSFC policy on labor substitution by machinery under the condition of rising labor costs using provincial panel data (2005-2021) and household survey data of two periods from three counties in Jiangxi Province. [Results] (1) In the backdrop of selective labor transfer and rising prices, farmers increasingly favored labor substitution by machinery. (2) HSFC policy enhanced effects on labor substitution by machinery. (3) Pronounced effects of HSFC policy were observed in grain-producing areas, regions with significant labor outflows, and among large-scale farmers. (4) The HSFC policy, through measures like reducing sloping land and improving rural infrastructure, effectively enhanced labor substitution efficiency. …”
